Calgary’s CoolIT Systems says it has increased global production capacity across its product lines at triple-digit rates over the past two years as global demand for artificial-intelligence infrastructure accelerates the shift toward liquid-cooled data centres.
The 25-year-old company, a pioneer in direct liquid cooling (DLC) for high-density computing, increased output of coolant distribution units (CDUs) and coldplates while developing technologies capable of cooling chips exceeding 4,000 watts and AI server racks surpassing 500 kilowatts.
“With the insatiable demand for liquid-cooling to fuel AI deployments, expertise and speed matter,” said CEO Jason Waxman. “CoolIT’s decades of experience in liquid cooling at scale is the reason we’re now providing gigawatt-level capacity to support the world’s most demanding datacenter customers.”
The company plans further production expansion in Canada, China, and Vietnam in 2026 alongside several new product launches.
AI Driving Data Centre Redesign
The announcement highlights how rapidly AI computing is reshaping infrastructure spending. Operators are increasingly redesigning facilities around liquid-cooled architectures as next-generation GPUs push far beyond the limits of traditional air cooling. Some accelerated computing systems now exceed 100 kW per rack, with future deployments expected to reach more than 500 kW.

Direct liquid cooling improves power usage effectiveness, increases compute density, and reduces reliance on large-scale air handling — factors that directly affect operating margins for hyperscale AI clusters.
CoolIT says its coldplates currently cool more than five million GPUs, CPUs, and AI accelerators and its technology is used in seven of the world’s top ten supercomputers, including the top-ranked Frontera system. The company counts four of the top five server OEMs and four of the five hyperscalers among its customers and provides technical support in more than 80 countries.
Calgary Roots to Global Infrastructure
Founder Brydon Gierl said the growth reflects a long journey from the company’s beginnings in a Calgary garage.
“It’s hard to believe the company I founded with three friends in Calgary over 25 years ago has grown to become a global technology leader,” he said. “Today we develop next-generation cooling technologies in our Calgary Liquid Lab while manufacturing at scale across multiple facilities worldwide.”
Founded in 2001, CoolIT has remained focused exclusively on liquid cooling as data centre power densities climbed from under 10 kW per rack to modern AI deployments hundreds of kilowatts higher.
The Calgary company was acquired by global investment firm KKR for a reported $365 million in 2023.
As AI infrastructure spending surges globally, CoolIT’s rapid manufacturing expansion signals that cooling — not just compute — has become foundational technology in the modern data centre.
